lPATENT g oFFicE Viirirvisiirvr G. OLIVER,y or MAMARONECK, NEW. YORK HAIRPIN` CLIP Application filed December 1, 1926. Serial No. 151,850.

I rihis invention relates to a hairpin clip` angularrelation tothe angle carrying bars and relatively close together. This arrange# l ment leaves a space between the channel turring irons and the lower surface oi' the floor.

It has been the practice to secure the channel 20 i'urring irons to the angle carrying bars by `hairp'in'clips which include biglit portions adapted rto embrace the channel ytuiring irons and leg portionsy adapted to be bent over the upper edges of the angle carrying'bars.

yThe application of these hairpin clips yhas f been somewhat difficult in the pastand it `has been common practice to first slip ay hairpin clip over the channel furring iron ailter the latter has been put in place against the lower ends of ther angle carrying barsso that the bent endsor legs of the hairpin clip overlie the upper edge of the angle carrying bar. To

bend these extended ends or legs downwardly `to embrace the angle carrying bar andto form, in effect.y hooks over the upper ledge oi the same, a practice has kbeen resorted to ywhich included the placing of a small pipe over these ends or legs .and bending them down as far yas possible with the use of this pipe. To get the maximum actionwo'fthis pipe, it has `been customary to bend' the pipe at an'angle so that it will contact with 'the channel 'urring irons or with #the angle f carrying baronly after the legsof the hairpin clip have rbeenbent to a considerable eX- tent. f However, it has not been possible to bend these legs by means of this pipe into their final position and thepractice has been, after the removal of the pipe, tocon'iplete the bending by striking the legs with a hammer.

' clinched.

The above practice has been attended by many disadvantages.y `The relatively small lspace between the floor and the channel y tui-ring irons affords an inconvenient working space'and the result has been that the 55 hammering down of the legs not'only consumes a comparatively great amount of time, but does not insure the clinchingof the hairpinclip on the angle carrying bar in such position that the channel urringirons will be held tightly and immovablyagainst the 'y angle carryingbars. There are many other disadvantages also incident to the use of the bendingpipe and hammer.

In my copending application, Serial No. 125,259, iiled July 27, 1926, I have illustrated a tool for applying the hairpin clips in such manner that all the above referred to disadvantages are overcome.

, The present invention yresides in the construction 'of a hairpin clip which is so `formed that its application will be greatly facilitated. f The hairpin clips which are at present in commercial use, are so formed that after they are put in place with the bight portion einbracing vthe channel urring iron and the leg portions engaging the upper edge ol the carrying bar, the legs must be immediately bent over said upper edge in order to maintain the hairpin clip in place.y The result is that each hairpin clip must not only be put in place but must be immediately clinched in place. Since this is true, itis impossible to first apply a series of hairpin clips and then clinch them, The present clip, however,

yis so formedthat a series oi' the clipsy may be put in place and the entire series then 'lhis, of course, 'results in a great saving of time and incidentally of expense and results inanemiiiently more satisfactory Job.

In the drawings: rFigure l is a fragmentary view showing the relation of the elements oflthe building constructionand the position of the old type of hairpin clip before it has 'been clinched;

. Figure 2 is a similar view' showing the haii'- pin clip constructed in accordance with the resent invention' after it has been put in place but before it has been clinched;

Figure 3 is a similar view showing the hairpin clip of Figure 2 in its clinched condition;

Figure 4 is a view taken at right angles to Figure 3; and

Figure 5 is a perspective view of the hairpin clip constructed in -accordance with this invention.

In the commercial art, a hairpin clip such as shown in Figure l, is almost universally used. This clip, as will be seen, from the-drawing, includes a body portion l, and legs 3, which are bent angularly with respect to the bight portion, the bending being 'carried to only such extent that the legs form obtuse angles with the body portion. This bending of the legs has 'been to facilitate the application of the vhairpins Lto Va carrying bar after the .bight portion has been engaged with the furring iron. After application the hairpin clips occupy .substantially :the position shown in Figure l. However, it is `:quite impossible to place a series tof clips in position before starting the clinching operation as the weight of the furringironzand the inclination of the .legs of the hairpin clips result in the slipping of the. hairpin clips on the upper edge of the Vcarrying bars and consequently, result in their displacement- YIt has, therefore, been necessary vas heretoforevlstated to iirst place a hairpin clip and then immediately clinch it before the next has .been placed. The disadvantagefof Vthis is perfectly patent.

The clip constructed inaccordance with the present invention, 'includes legs which 'are so formed that the clip can be snapped in place, the engagementy"of the 'legs with the upper edge of the carryingbar's'willbe,maintained and the furring irons held inplace irrespective of any vclinching operation. Therefore, a

seriesfof'h'airpin clips of'thisconstruction may be snapped in place to .position the furring 'iron 'and after having Lbeen Vsnapped in place in vthe furring position the rsuccessive clips of the series may be clinched. Y

'The clip lwhich is imadeprieferably of wire includes a 'bight portion l, which is adapted to-engagethe furring iron 2,=and legsv, which are adapted to tbe snapped over the upper edge of theV carrying bar .4, which carrying bar is supported bystoggles hanger '5, which depends from the floor of Vthe building 6.

At the ljunction 'between the legs 3 and-the bight vportion 1 -of the hairpin clip, the wire isbent to form seats 7 'which are adapted to marked 9, adjacent to their junction with the seats 7, is yless than the distance between the upper edge of the carrying "bar and `the lower edge of the furring iron. Zhen the hairpin is pushed into position with fthe legs overlying the upper edge of the carrying bar, the legs being resilient will yield to permit the forcing of the hairpin clip in place. Then the hairpin clip reaches a position such that the upper edge of the carrying bar is aligned with the seats 7 of the clip these seats will snap over the said upper edge and the hairpin clip Will be held in place, in turn maintaining the 4proper relation between the carrying bar and the furring iron.

This construction of hairpin clip not only facilitates the application of the clip by the old method which is hereinbefore described but also kby the new .method and by means of the new tool which l have described in my compending application hereinbefore referred to. Y ltwill be understood that the arms, 3, of the clip may be clinched into'position either by forcing or hammering them down in place or by pulling or drawing them down as by a tool such as shown in my prior application referred to above. As the particular method or means resorted to do not form any part of this invention, no detailed description is presented and the invention is not confined in Ythis respect. y

lVhile l have described a particular embodi- 'met of my invention, it is to be understood that many modifications may bemade within lthe spirit of the invention and without departing from the scope of the claims and l, furthermore, do not wish to be limited to the particular embodiment illustrated.

I claim: n

l. A clip .for supporting a member from another member comprising a bight portion for the accommodation of the first member and resilient leg portions adapted to be snapped over the second member, said leg portions eXtending angularly from the bight portion and having their free ends disposed at less vertical distances from the heel of the bight portion than the jointed ends to provide concave downward bends serving as seats between the free ends and jointed ends for disposition on the second member.

2. A clip of the class described comprising a substantially U-shaped member having the free ends of the legs offset angularly and disposed in spaced, substantially parallel relation, said legs being joined to the body of the U-shaped Vmember in concave downward ybends providing seats for disposition on a supporting member, said legs possessing resiliency for exert-ing a resilient grip on said supporting member whendisposed thereon.

3. A clip for suspending one member from a lsecond member comprising a unitary element having a portion for supporting the first member, a vertical portion extending from the supporting portion, and an oblique portion extending from the :top of the vertical portion, said oblique portion being joined to the vertical portion in a concave downward
